工件以圆孔在间隙配合的定位轴(或者定位销)上定位是一种常用的定位方法,其定位误差的分析计算在许多文献资料中已有论述,但是以往这些论述均是讨论采用单套夹具,而且一套夹具上只有一根定位轴的情况。为了提高生产效率,一套夹具上往往设计有多根定位轴以便装夹多个工件,在自动线上往往采用随行夹具,在整条自动线上配置有许多套夹具,传送装置将装夹有工件的各套夹具依次送到各台机床上去 The positioning of a workpiece with a locating axis (or locating pin) with a circular hole in a clearance fit is a commonly used method of locating and the analysis of locating errors has been discussed in many literature, but in the past these discussions have dealt with the use of a single set Fixture, but also a fixture on the positioning of a shaft. In order to improve the production efficiency, a set of fixtures is usually designed with a plurality of positioning axes for clamping a plurality of workpieces. In the automatic line, the follow-up fixture is often used. Many sets of fixtures are arranged on the whole automatic line. The conveyer will clamp the workpiece Each fixture in turn sent to each machine
